Wasted Ecological Effort

I noted on my arrival at Charles De Gaulle yesterday that the ecological efforts of the airport may be well intended, but are not always particularly effective. The Gentleman’s toilet (I can’t vouch for the Ladies) of Terminal 2F at the baggage carousel area is fully automated (water, soap, air dryer). Unfortunately, however, when you go to dry your hands, the air of the dryer, which is positioned right on top of the basins, provokes the automated water faucet to start pouring out water again. I wonder how much water is wasted by people drying their hands! Not famous engineering. And I am certain that no one, in a 35-hour week, has the time to fix the problem.
